(Go) FTP Sync Download Tree w/ Must-Match Directory Constraints

Demonstrates how synchronize a directory tree in the download direction, but only entering directories matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

Chilkat Go Downloads Go Package for Windows, MacOS, Linux, Alpine Linux, Solaris

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    ftp := chilkat.NewFtp2()

    ftp.SetHostname("ftp.something.com")
    ftp.SetUsername("my_login")
    ftp.SetPassword("my_password")

    // Connect and login to the FTP server.
    success := ftp.Connect()
    if success != true {
        fmt.Println(ftp.LastErrorText())
        ftp.DisposeFtp2()
        return
    }

    // Set the current remote directory to the root of
    // the tree to be downloaded.
    success = ftp.ChangeRemoteDir("/subDir1")
    if success != true {
        fmt.Println(ftp.LastErrorText())
        ftp.DisposeFtp2()
        return
    }

    // Possible synchronization modes are:
    // mode=0: Download all files
    // mode=1: Download all files that do not exist on the local filesystem.
    // mode=2: Download newer or non-existant files.
    // mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server..
    // mode=5: Download only missing files or files with size differences.
    // mode=6: Same as mode 5, but also download newer files.

    // Imagine our remote directory tree has these files and directories:

    // 	accentedLatin1.txt
    // 	accentedUtf8.txt
    // 	alice.key
    // 	anter_cert.pem
    // 	chiliPepper.gif
    // 	helloWorld.pdf
    // 	abc/chiliPepper.gif
    // 	abc/ghk/
    // 	data/chiliPepper.gif
    // 	data/xyz/dkimHtmlBody.txt
    // 	data/xyz/dkimVerifyTest.eml
    // 	data/xyz/emailForCreateDsn.eml
    // 	text/frenchUtf8.txt
    // 	text/helloWorld.txt
    // 	text/PolishEmailBody.txt
    // 	text/something/

    // Only enter remote directories named either "data" or matching "x*"
    ftp.SetSyncMustMatchDir("data; x*")
    mode := 0
    success = ftp.SyncLocalTree("c:/temp/subDir1",mode)
    if success != true {
        fmt.Println(ftp.LastErrorText())
        ftp.DisposeFtp2()
        return
    }

    success = ftp.Disconnect()

    // Show the files downloaded.
    fmt.Println(ftp.SyncedFiles())

    // Output showing the files downloaded:

    // accentedLatin1.txt
    // accentedUtf8.txt
    // alice.key
    // anter_cert.pem
    // chiliPepper.gif
    // helloWorld.pdf
    // data/chiliPepper.gif
    // data/xyz/dkimHtmlBody.txt
    // data/xyz/dkimVerifyTest.eml
    // data/xyz/emailForCreateDsn.eml

    ftp.DisposeFtp2()
